Adrian Otaegui holds a two-shot lead after the first round of the Lyoness Open after a superb eight-under-par 64 start from the Spaniard.
Otaegui, who came through qualifying school in November to earn his place on the European Tour, produced a faultless performance at the Diamond Country Club in Atzenbrugg on Thursday.
He made the turn at four under and three successive birdies from 14 to 16 and a further gain at the last gave Otaegui a two-stroke advantage over Bjorn Akesson, whose only blemish in his six-under 66 came at the par-four 17th.
Gary Stal, whose round featured a pair of eagles, and Zander Lombard are level in tied third at five under with Kristoffer Broberg and Gregory Bourdy a shot further off the pace.
"Of course I'm very pleased. I played well from the beginning until the end and didn't make too many mistakes," Otaegui said.
"I'm hoping now I can play four days in the same way so that's the main goal."
Joost Luiten, a winner in 2013, is among nine players five shots adrift at three under, while defending champion Chris Wood - the highest ranked player in the field - has work to do the retain the title.
Starting at the 10th, BMW PGA Championship winner Wood was three under with seven holes left but three bogeys and a birdie in the final five saw him finish on one under.
And he was relieved to get home with a 71 having found the water on the ninth - his last hole. Wood producing a superb recovery to the edge of the green before two putting to complete his day.
